1. Introduction
ADI12-8(USB)GY 1
1. Introduction
Summary
This product is a USB2.0 compatible terminal module that extends the analog input
function of USB port of PCs. This product features 8ch 12-bit analog input and is
isolated from the bus line to the PC. The signal lines can be connected directly to the
terminals on this product. To simplify use in embedded applications, this product
includes a bracket for attaching to a 35mm DIN rail. The number of input channels
can be increased by purchasing an optional device module. Windows driver is
bundled with this product.
Features
- Conversion speed 10µsec/ch+20µsec, 12bit resolution, Difference input 8ch
This product includes analog inputs (10µsec/ch + 20µsec, 12-bit, differential inputs,
8ch). Compatible to USB1.1/USB2.0 and capable to achieve high speed transfer at
HighSpeed (480 Mbps).
As this product can be used on any PC that supports USB, it is suitable for use with
notebook PCs that do not have PCI bus expansion slots. If using with a desktop PC,
this product can be connected easily without needing to open the computer's cover.
- Isolated from the bus by a digital isolator
This product is isolated by a digital isolator which improves the noise performance
with respect to the PC.
- Equipped with the buffer memory (256K data) which can be used in either
FIFO or ring format
This product includes buffer memory (256K data for analog input) which can be used
in either FIFO or ring format. You can perform analog input in the background,
independent of software and the current status of the PC.
- Windows compatible driver libraries are attached.
Using the attached driver library API-USBP(WDM) makes it possible to create
applications of Windows. In addition, a diagnostic program by which the operations
of hardware can be checked is provided.
Sampling can be driven by a clock or by various triggers
Sampling can be started and stopped by software and level comparison (compares the
level of a specified channel with a specified compare level value) triggers.
The sampling period can be controlled by the internal clock (high-precision timer
included on the board).

1. Introduction
2ADI12-8(USB)GY
- Easy to increase the input channels using an expansion module
Adding optional modules (up to 3 units) can easily increase the input channels. The
unique structure for connection by stacking enables easy and compact system
configuration.
- Screw-less connector plug facilitating wiring and plugging/unplugging
Wiring and plugging/unplugging are easy as the screw-less connector plug is used.
- Capable of being mounted on 35-mm DIN rails
This product is equipped with an attachment for mounting on 35-mm DIN rails on the
back, allowing this product to be attached onto and detached from DIN rails.
- LabVIEW is supported by a plug-in of dedicated library.
Using the dedicated library makes it possible to create each application for
LabVIEW.

Support Software
It is suggested that support software produced by our company should be used
according to the goal and development environment.
Driver Library API-USBP(WDM) (Bundled)
It is the library software, and which supplies command of hardware produced by our
company in the form of standard Win32 API function(DLL). Using programming
languages supporting Win32API functions, such as Visual Basic and Visual C++ etc.,
you can develop high-speed application software with feature of hardware produced
by our company.
In addition, you can verify the operation of hardware using Diagnostic programs.
For more details on the supported OS, applicable language and new information, please visit the

Setting a Module ID
The host computer distinguishes and keeps track of the modules of same model by
assigning Module IDs to them. Factory settings “00” can be used when only one
module per model is connected to one computer.
Each module should be assigned a unique Module ID in the range of 00 - 7Fh when
several modules with the same model are being connected.
There are two rotary switches, moreover, “x16” and “x1” represent high bits and low
bits of Module ID respectively.
